The Free Syrian Army affiliate "Mountain Hawks Brigade" has released footage of combat operations around and within the embattled city of Aleppo. In three videos published on Youtube, the brigade's fighters are shown employing heavy weaponry to dislodge Islamic State fighters and conduct anti-air operations.

In this image, a fighter prepares to load an M69A 82mm Yugoslavian mortar during combat operations against the Islamic State near a village north of Aleppo. Soviet-era munitions are frequently used by all sides in the conflict.

Fighters operate a heavy machine gun to fire on a twin engine fighter aircraft in Aleppo. A number of jets have been shot down by anti-aircraft weapons throughout the war. Jaish al-Nasr said it downed a Syrian warplane with anti-aircraft guns in March, though the Syrian Observatory for Human Rights disputed this claim and reported the aircraft was destroyed with heat-seeking missiles.
